01 / How it works
Vacuum excavation and
non-destructive digging.
High-pressure water breaks up the ground; a vacuum lifts the spoil straight into the truck. Nothing mechanical touches what's buried. It's how you dig within centimetres of a live gas main or a fibre run without putting a bucket through it. Also called NDD, hydro excavation or hydrovac.
Non-destructive digging
No mechanical contact

02 / Applications
What we
dig.
If it's near something you can't afford to hit, this is the method.
-
Potholing & service location
Exposing known services to confirm depth and position. -
Trenching near services
Trenching tight to existing infrastructure without risk. -
Footings & pier holes
Non-destructive digging for new footings and pier hole cleanouts. -
Pit & manhole cleanouts
Pits, manholes and stormwater gross pollutant traps. -
Asset proving
Confirming what's actually underground before works start. -
Power pole excavation
Digging around poles and stobie bases safely.
03 / The difference
Why not just
use an excavator?
Because a bucket doesn't know what's underneath it. Strike a water main, a gas line or a fibre run and the repair, the downtime and the incident report all land on the job.
Vacuum excavation removes that risk entirely, and it reaches places a machine physically can't.

06 / Common questions
Vacuum excavation
questions, answered.
What is non-destructive digging?
Excavation using high-pressure water and a vacuum instead of a mechanical bucket. The water breaks up the ground, the vacuum lifts the spoil into the truck, and nothing solid ever contacts what's buried.
When do I need vacuum excavation instead of an excavator?
Any time you're digging near live services, water, gas, power, telecommunications, or anywhere a strike would be expensive or dangerous. It's also the answer for tight access where a machine won't fit.
Is it the same as hydro excavation or hydrovac?
Yes. Vacuum excavation, hydro excavation, hydrovac and NDD all describe the same method. The terminology varies by industry more than by technique.
Do you do general excavation and earthmoving?
No. We're a non-destructive digging specialist: potholing, trenching near services, footings, pier holes and pit cleanouts. For site cuts, land clearing or bulk earthworks you want an earthmoving contractor.
Can you dig where an excavator can't reach?
Often, yes. The hose reaches into confined and awkward spaces a machine can't get to, which is one of the main reasons the method gets used.
Do you work with councils and civil contractors?
Yes. We're an LGAT Preferred Supplier and work across Tasmanian local government, alongside builders, civil contractors, utilities and other trades.
